Desperate efforts

All the water pressure control diaphragm valves and water tubes were replaced last night except #1 working chair, in spite of finger aches on both sides, I made desperate efforts.
Remembering the time of starting our new laboratory, one of my relative who is in Morita Factory in KYOTO exerted himself alone on setting 4 working chairs. It's is not a difficult task to imagine his ultimate labor, probably he must have exhausted at that work. He had many experience on the work as a professional, generally one chair is treated by one engineer taking one day, but he did 4 by his own efforts! Now I have realized again, he did best than best!

Remembering his great tasks at that time, I have to do the work anyway, replacing parts for # chair without any selfish complaint.
